GRAIN-DOOR FOR CARS.

Specification of Letters Patent.

Patented Oct. 29, 1907.

Application filed July 20, 1907- Serial No, 384,706-

To all whom "it may concern:

Be it known that 1, CHARLES E. Mares, a citizen of the United States,residing at Havana, in the county of Sargent and State of North Dakota,have invented certain new and useful Improvements in Grain-Doors forCars; and I do hereby declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

My invention has for its object to provide an improved grain door forcars, and to this end it consists of the novel devices and combinationsof devices hereinafter described and defined in the claims.

In the accompanying drawings which illustrate the invention, likecharacters indicate like parts throughout the several views.

Referring to the drawings, Figure 1 is a view in outside elevation,showing the intermediate portion of a car body and illustrating myimproved grain door ap plied thereto. Fig. 2 is a detail in verticalsection, with some parts broken away, taken approximately on the line 00x of Fig. 1. Fig. 3 is a horizontal section taken on the line :0 x ofFig. 1, some parts being broken away. Fig. 4 is a detail in section onthe line on x of Fig. 1, some parts being broken away. Fig. 5 is a viewin elevation, looking at the inner side of the grain door and side wallof the car body, some parts of the latter being broken away. Fig. 6 is adetail in vertical section, taken approximately on the line at x of Fig.1,

some parts being broken away; and Fig. 7 is a detail on an enlargedscale, taken on the line 90 x of Fig. 3.

The car body 1, which is of the usual or any suitable construction, isprovided with the customary side door openings 2 to which my improvedgrain doors are applied. The grain door is made up of two sections 3 and4 which at their upper outer corners are provided with hinges 5, theouter wings of which are slit and pressed laterally to form verticalseats 6. Vertically extended guide rods 7 secured at their lower ends tothe car fioor and at their upper ends to the upper portion of the doorframe extend inward from the door posts 2 and are provided near theirupper ends with bent supporting ledges 8. The lower portions of theseguide rods 7 are also shown as secured to the door posts by smallbrackets 9. The upper and intermediate portions of the guide rods 7 arepassed through the seats 6 of the hinges 5 so that the grain doorsections are free for vertical movements thereon. The outer edges of thedoor sections 3 and 1 overlap with the inner faces of the door posts 2*,and the inner edges of said sections overlap each other. These doorsections are preferably constructed from sheet metal plates and they arereinforced by horizontally extended bars, shown as in the form of angleirons 10. When the door sections are both placed in operative positions,as

shown in Figs. 1, 2 and 5, the adjoining ends of horizontally alinedangle bars 10 of the two door sections lap by each other, and theprojecting inner edge of the door plate 4 is engaged between thelaterally bent inner edge of the door plate 3 and its cooperatingrigidly secured angle bars 10. "his construction is also wellillustrated in Fig. 4, wherein the two door sections are separated bycdgewise movements.

Rigidly secured to the angle bars 10 of the door section 3, close to theinner ends thereof, is a vertically extended tie bar 11, and to this tiebar a sliding lock bar 12 is connected for limited vertical movements bymeans of slot and pin connections 13. At its upper and lower ends,respectively, it is provided with laterally and upwardly projecting lockbolts or projections 14 and 15 which. when the bar 12 is moved upward,are adapted to be passed through coincident perforations 16 in theoverlapped laterally projecting flanges of the horizontally alined anglebars 10, and thus lock the two door sections against horizontal edgewiseseparation. The lock bar 12 is adapted to be raised and lowered by meansof a lever 17 which, as shown, is pivotally connected to a stud 18,which stud is supported from the tie bar 11 and projects through a slot1S in the lock bar 12. At its short end the lever 17 is provided with aprojecting lock bolt 19 that is adapted to work through co-incidentperforations in the overlapping laterally projecting flanges of theintermediate angle bars 10, to thus assist the lock bolts l tand 15 inholding the door sections together. To the long end of the lever 17 ispivoted the upper end of a lock plunger or rod 20, the lower end ofwhich works through a guide 21 on the lower angle bar 10 of the doorsection 3 and is adapted to be forced into a suitable seat 22 formed inthe door sill, as best shown in Fig. 1. Then the lock plunger or rod 20is forced into the seat 22 it affords a stop for preventing the outwardbulging of the grain door.

To prevent the two grain door sections from moving vertically, the onewith respect to the other, when in working position, a lock in the formof a short channel bar section 23 is shown as pivoted at 24 to thelaterally projecting flange of the intermediate angle bar 10 of the doorsection l. This channel-shaped lock, when moved into the position shownby full lines in Fig. 3, is adaptcd to embrace the overlapped laterallyprojecting flange portions of the two intermediate angle bars 10 (seealso Figs. 1 and 7).

By an upward movement of the free end of the lever 17, the lock bolts14, 15 and 19, will be simultaneously withdrawn from their seats in theflanges of the angle bars 10, and the lower end of the lock bolt will bewithdrawn from the lock bolt seat 22 in the door sill, therebydisconnecting the intermediate overlapping portions of the two doorsections and permitting the same to be forced outwardby the pressure ofthe grain, as indicated by dotted lines in Fig. 3. When it is desired toremove the grain door bodily into an inoperative position, it is slidupward until the perforated wings of its hinges 5 are moved onto theledges 8 of the guide bar 7 and when this is done the grain door may bemoved pivotally against the roof of the car and there secured by anysuitable means (not shown).

Gravity held lock pieces are preferably pivotally supported upon thedoor posts into a position to normally engage the upper edge of thegrain door and thereby hold the same closely engaged at its lower edgewith the door sill. As shown, short chains 26 are attached to the lowerportions of the door sections 3 and 4 and are provided with hooks 27that engage with the lower portions of the guide rods 7. These chains 26assist the hinges 5 in holding the grain door sections to the body ofthe car after the two door sections have been separated and forcedoutward by the pressure of the grain.

What I claim is:

l. The combination with a twopart grain door, the sections of whichoverlap at their inner edges and are provided with overlapping laterallyprojecting flanges, of a lock bar slidably mounted on one of said doorsections, and having lock bolts engageable with co-incident perforationsin said overlapped flanges, to lock together the two door sections,substantially as described.

2. The combination with a two-part grain door having upper, lower andintermediate reinforcing angle bars, the flanges of which overlap, of alock bar slidably mounted on one of said door sections and provided withprojecting lock bolts engageable with co-incident perforations in theoverlapped flanges of the upper and lower angle bars, a lever pivotallyconnected to the grain door section to which said bar is applied, andalso pivotally connected to said lock bar, said lever having aprojecting lock bolt adapted to en gage co-incident perforations in theoverlapping flanges of said intermediate angle bars, substantially asdescribed.

3. The combination with a two-part grain door having overlapping flangesat their inner faces, of means for locking said two door sectionsagainst endwise separation, and a channel shaped lock piece pivoted toone of said flanges and engageable with two of the overlapping flangesto prevent vertical movement of one of the door sections with re spectto the other, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.
